DIFFRACTION BY AN ELASTIC WEDGE WITH STRESS-FREE BOUNDARY: EXISTENCE AND UNIQUENESS

This preprint was accepted July 3, 2003

ABSTRACT:
Applying the spectral function techniques, worked out in \cite{CL}
we prove existence of solution to the problem of plane (and
spherical) wave diffraction by an elastic wedge with stress-free
boundary conditions. We also formulate radiation conditions, under
which the uniqueness holds.
